一些英语建议😄: 
 1)你怎么了? 
 What's wrong with you?(❌) 
 这句话不好!It sounds like
 an insult (你有问题吗,你有毛病吗)?!!😱。请不要说这句话😱!! 如果你想对别人关心,你可以尝试:
Are you ok?(✔)
2)I beg your pardon?
这句话太老了。“Pardon?”仍然在使用,但是年轻人不常说了。你可以尝试:
Sorry? (✔)
Could you please say that again?(✔)
3)爬山
这个单词我曾经写过,但是我还想再写一次。
go climbing/climb a mountain不是我们一般的爬山运动🤔(❌)。It implies specialized equipment and technical difficulty。climbing要求很多专业的设备。比如:climb steep rocky slopes (攀岩!😱)。如果你想表达简单的爬山锻炼,你可以说:
Go hiking(✔)
